How is it possible for new crust to be formed without increasing the surface area of the Earth?
Crust is recycled in subduction zones at the same time it is created at mid-ocean ridges
New crust is underwater where it sinks
New crust breaks more easily than old crust
The oldest crust just breaks apart as the plates move
The average density of continental crust is 2.8 g/cm3 and the average density of oceanic crusts is 3.2 g/cm3. If these two plates came together, what would happen?
The two plates would push apart and form a rift zone.
The oceanic plate would rise up over the continental plate.
The oceanic plate would sink under the continental plate.
The two plates would meet head on and rise up to form mountains.
Scientists use ______ to map the ocean floor
radar
pulsar
lidar
sonar
